Ok, so I changed my fuel filter (stock filter) and after following the directions on a thread is this section when I went to drive my truck it is WAY down on power. The darn trans is shifting at different RPM points as well. I can barely achieve 55mph! I filled the filter with Lubro Molly diesel purge like I always do when changing the filters on my TDI Jetta. I pumped the primer and bled the system to the point of fuel squirting out the nipple. Then I tightened her up and went for a drive.

I DONT GET IT!

Frustrating.

I had that problem once when running my first couple tanks of biodiesel. I think it was the bio cleaning out the fuel system and temporarily clogging the fuel filter. A simple restart solved the problem.

Not sure if that helps you, but I would check the priming of your system. What is Lubro Molly diesel purge?

Thanks. I unplugged the negative terminal resetting the computer and for whatever reason it runs fine again.

Diesel purge is stuff to fill your filter with when you install a new filter. You shouldnt install a filter empty. Diesel purge cleans your system.

Glad it seems to have fixed itself. I thought that you can install a new filter dry, then just prime the system to get all of the air out and fuel into the filter? That is what I did when I changed my filter.

Yes you can install the filter dry and use the prime and purge to fill it up before restart. Have done it that way 3 times on different CRDs with no problem. 2 things to remember 1) be sure that you don't leave the old center post gasket on (if you do the double gasket will cause a massive air leak problem and 2) don't use unfiltered diesel (includes diesel from your old filter) if you like to fill your filter before install for obvious reasons.

air air and more air.... bleed it, if it doesn't work replace the incoming fule line from the tank to the fuel head and get rid of its quick connectors.
